VAPORIZER AND PRIMER.

Application filed September 21, 1921. Serial No. 502,272.

T 0 all whom it may cancer n:

Be it known that I, ERNEST O. WoLFr, a citizen of the United States, anda resident of Gillette, in the county of Morris and State of New Jersey,have invented certain new and useful Improvements in Vaporizers andPrimers, of which the following is a specification.

This invention has reference to a device for attaching to a motor of theinternal combustion type, that will facilitate the operation of theengine and particularly relates to means for priming the engine toassist in starting the motor. v

The object of this invention is toprovide in a device of this character,means for permitting the introduction into the manifold or similar partof a motor, of a fluid that will quickly vaporize to furnish a gas tofacilitate the starting, of the engine, and which will retain the fluidinside of the manifold in a portion that is exposed to the manifold topermit a ready evaporation.

In the accompanying drawing showing one embodiment of my invention,

Fig. 1 is a side elevation of the priming device.

Fig. device.

This invention comprises essentially a priming device to be attached tothe manifold of an explosive engine.

This device as shown comprises a body portion 2 of tubular form havingthe usual priming cup and valve 3, screwed into one end that is threadedfor this purpose. The latter is provided with a plug 4.- and a handle 5so that a liquid can be poured into the upper cup portion 6 and flowinto the body 2 when the valve is opened. Then the valve is closed asusual to prevent escape of the pressure and gas in the manifold. Thebody 2 has an extension 7 that has screw threads 8 at the middleportion, with-the end portion 9 closed at the end 10 and provided withseveral openings at the top of the end portion, preferably by a numberof saw-cuts 12. The member 2 with the parts 2 is a plan view of thesame. 3 is a vertical section through the 7 and 9 are preferablyintegral and may be a casting.

The body has the threaded portion 8 screwed into a suitable threadedaperture in the manifold, as indicated in Figs. 1 and 2, and lockedtherein with the valve cup extending upward and also the slots at theinner end. The valve is opened and a suitable liquid such as ether andgasoline is poured into the cup 6 that will flow through the tube andnot escape atthe end, except through the slots at the top, whereby thetube will remain practically filled with this fluid. The valve is closedand the motor star-ted and the suction in the manifold will act throughthe slots and draw the gas or vapor out of the body portion until it isexhausted, which will form the desired mixture and greatly assist instarting the motor.

This priming device can be used in combination with a moisture. device,and for this purpose it is provided with a tubular extension 14 at thetop of the body portion 2 adapted to receive a pipe 15 that leads to asuitable receptacle for water.

It will be seen that a device as shown in Fig. 2 is very simple andeconomical to produce, being merely a casting that is threaded atseveral portions and provided with the slots, and the conventionalpriming cup 3 is applied at one end. This device as attached to themanifold in place of the usual priming cup 3 at its threaded portionthat will be of the same size. Where the motor is provided with thepriming cup as 3, it is only necessary to remove the same and apply thepriming cup to the body 2 and screw the body into the threaded openingin the manifold from which the priming cup was removed;

What I claim is:

1. A priming device, comprising a tube externally threaded, a valve onthe outer end of the tube and provided with a priming cup, the tubebeing closed at its inner end beyond the threads and provided with smallopenings in the top of such portion.

2. A priming device comprising a tube threaded at its middle portionwith the inner end closed, the tube having several narrow slits at theupper part of the inner end portion beyond the threads, and a valve onthe outer portion of the tube.

3. The combination with amanifold of a priming device comprising a tubeprojecting into the manifold, a valve on the outer end of the tube andprovided with a priming cup, the tube being closed at its inner endportion beyond the threads and provided with small openings in the topof such portion.
